This is a city killer, not a continent killer. Wishing for few hundred thousand innocent people to die is just pure evil - it has no effect on overpopulation.
Overpopulation is eugenicist propaganda anyway
Owls and rabbits aren't the ones burning fossil fuels. Since I was born, 74% of the animals have gone.
Yeah, overpopulation is long past, we're at apocalyptic now.
Sounds like a ~~capitalism~~ overconsumption problem more than population
Well, it's a problem that will solve itself. Most estimates say that the world's popularion will peak around 2080 and start to decline after that.
I hadn't seen those numbers, is it a result of anthropogenic climate change?
More a result of countries managing to get over the industrial revolution population spike, and getting into the modern age. Once you have access to modern medicine, and the birth mortality and child mortality rates plummet, people stop having so many kids.
Depends on how fast its going when it hits
It's currently moving at about 12,000 kph and will be slightly sped up to 17,000 kph if it actually hits us. That is not a significant enough portion of C to be anything but a city killer. This thing isn't even a Tsar Bomba in terms of energy output. More like a Mark 17.

Regrub just said can we make it go faster, so i guess it would need to be increased much much more than 17,000 kph, which seems slow for galactic/cosmic speeds.
Wonder how much more energy it would need.
Someone get Randal Monroe on this stat!
Lol
I think you'd need to nearly double the velocity for it to be remotely close. I think I saw something like 30-40k km/h before it's at that level
